1. Introduction
This document gives a description on how to get started with the PN7120 NFC-Controller
SBC Kit. This document provides a step by step guide to the installation procedure of the
hardware and the software. Finally it shows PN7120 NFC Controller functionalities
through demonstration application.
1.1 OM5577/PN7120S demo kit
OM5577/PN7120S kit is a high performance fully NFC compliant expansion board for
both Raspberry Pi (refer to [1] for more details) and BeagleBone (refer to [2] for more
details). It meets compliance with Reader mode, P2P mode and Card emulation mode
standards. The board features an integrated high performance RF antenna to insure high
interoperability level with NFC devices.
The kit is composed of 3 printed circuit boards and a MIFARE Ultralight EV1 card.

1.2 Linux driver support
PN7120 NFC Controller is supported under GNU/Linux system using the NXP Linux
libnfc-nci software stack (for more details, refer to AN11697 available on PN7120
Product Web Page [5]). The Raspberry Pi and BeagleBone Linux demo images include
the complete stack (Kernel mode driver, User mode library and demo application)
allowing to demonstrate the NFC functionalities offered by the PN7120.
1.3 Android driver support
PN7120 NFC Controller is supported from the official Android Open Source Project (refer
to [7] for more details) with the addition of dedicated patches available through PN7120
Product Web Page [5] (refer to AN11690).
The BeagleBone Black demo image is based on this concept.
1.4 Windows IoT driver support
PN7120 NFC Controller is natively supported as Proximity platform device by Win10 IoT
OS through the universal NFC device driver model, more details can be found in relative
pages on Microsoft website (refer to [8]). For instructions on how to install this driver refer
to AN11767 available through PN7120 Product Web Page [5].
The Win10 IoT Raspberry Pi 2 demo image is based on this concept.

2.2.1 Raspberry Pi A/B (old models)
On the old models, the Raspberry Pi Interface Board connector fit perfectly the
Raspberry Pi one. Assemble the boards as shown in figure below, removing first the 4
white plastic spacers:
Fig 3. OM5577/PN7120S and Raspberry Pi B model stacked together
2.2.2 Raspberry Pi A+/B+ and Raspberry Pi 2 (new models)
The Raspberry Pi new models have a 40-pin connector allowing to connect an expansion
board. The Raspberry Pi Interface Board only make use of the first 26 ones for
compatibility reason with the previous Raspberry Pi models. Assemble the boards as
shown in figure below:
Fig 4. OM5577/PN7120S and Raspberry Pi B+ model stacked together
2.3 Software setup
Prepare a SD or MicroSD card, with the downloaded Raspberry Pi demo image
(http://www.nxp.com/documents/software/OM5577_Rbi.html or
www.nxp.com/redirect/nxp.box.com/OM5577-PN7120S-Rpi-Win10IoT), following the
installation guidelines:

2.4 Starting NFC demo
2.4.1 Linux image
Insert the SD or MicroSD card in the Raspberry Pi. Connect HDMI Display, mouse and
keyboard. Then power-up the Raspberry Pi by plugging the USB power cable.
The Raspberry Pi boots and displays the Raspbian GUI:
Fig 5. Raspbian GUI
Open a terminal and browse to the Linux libnfc-nci stack directory (refer to chapter 1.2 for
more details about the Linux NFC software stack).
$ cd ~/linux_libnfc-nci
Refer to chapter 4 for the following procedure.

2.4.2 Win10 IoT image
Insert the SD or MicroSD card in the Raspberry Pi 2, connect HDMI Display, and then
power-up the Raspberry Pi by plugging the USB power cable.
The Raspberry Pi boots and displays the “Proximity_BasicTest” application for
demonstration of NFC functionality.
The application consists of a simple graphical interface, displayed on the HDMI output of
the Raspberry Pi. It will react when NFC devices or tags are made proximate to the
PN7120 antenna by displaying short messages:
